摘要: 摘要: 
提出了一种由单帧立体图像实现一般路面图像逆透视变换的方法.针对双目视觉得到的路面垂直轮廓进行B样条建模,利用建模得到的路面高度代入路面图像成像过程中,从而实现一般路面的逆透视变换.实验表明,通过该方法能有效地实现上下坡等一般路面图像的逆透视变换. 关键词:

Abstract: This paper put forward an inverse perspective mapping method for general road. By modeling the vertical profile of a road using stereo vision, and substituting the modeled height into the process of road image formation, an inverse perspective mapping of a general road can be achieved. The experiment validates that the method is capable to deal with the situations of inverse perspective mapping such as downhill, uphill or uneven road image.  

Key words: inverse perspective mapping, bird’seye view, road modeling, stereo vision
